R-902+, R-104, R-105 & R-706 Specification Guide for Manufacturers
Titanium dioxide (TiO₂) is one of the most important white pigments used across paints, coatings, plastics, masterbatches, PVC profiles, and other industrial formulations. However, selecting the right TiO₂ grade is not simply about choosing the whitest or most opaque pigment. Manufacturers also need to consider dispersion, tint strength, weatherability, chalk resistance, gloss, processing behaviour, and the final application.
Among the established TiO₂ product ranges, Chemours Ti-Pure offers multiple rutile grades designed for different formulation requirements. Four grades that are particularly relevant for industrial buyers are Ti-Pure R-902+, R-104, R-105, and R-706.
This guide explains the key differences between these grades and helps manufacturers, formulators, and procurement teams understand where each grade may fit best.
Understanding the Chemours Ti-Pure Product Range
Chemours Ti-Pure titanium dioxide pigments are designed for different industrial applications rather than following a single universal formulation approach.
The four grades discussed in this guide serve different purposes:
- R-902+ – versatile grade for interior and exterior coatings
- R-706 – coatings grade focused on gloss, durability, and dispersion
- R-104 – plastics grade designed for highly loaded thermoplastic masterbatches
- R-105 – durable plastics grade designed particularly for outdoor applications
Therefore, manufacturers should select the grade according to the resin, coating system, processing conditions, and required end-use performance.
Ti-Pure R-902+: Versatile TiO₂ for Coatings
Ti-Pure R-902+ is a rutile titanium dioxide pigment manufactured using the chloride process. It is designed for both interior and exterior coatings and offers a balance of hiding power, chalk resistance, gloss, and dispersion.
For coating manufacturers looking for a multipurpose TiO₂ grade, R-902+ can be considered for applications such as:
- Architectural coatings
- Interior semigloss paints
- Exterior finishes
- Industrial coatings
- Powder coatings
One of the major advantages of R-902+ is its dispersion performance. Good dispersion can help manufacturers achieve consistent optical performance while controlling processing requirements.
The grade has a minimum TiO₂ content of 93% and a typical specific gravity of 4.0. Chemours also reports a median particle size of approximately 0.405 µm.
Why manufacturers consider R-902+
R-902+ can be useful when a formulation requires a balanced combination of:
- Hiding power
- Tint strength
- Brightness
- Gloss
- Dispersion
- Chalk resistance
It is therefore better viewed as a versatile coatings grade rather than a specialised plastics pigment.
Ti-Pure R-706: Gloss and Durability for Demanding Coatings
Ti-Pure R-706 is another chloride-process rutile TiO₂ grade, but its positioning is different from R-902+. Chemours describes R-706 as a universal grade for coatings where high gloss and durability are important.
It is suitable for solventborne and waterborne systems and can be used in architectural, industrial, and automotive coating applications.
R-706 is characterised by:
- High gloss
- High durability
- Excellent dispersibility
- Easy wet-in
- Good hiding
- Blue undertone
The grade has a minimum TiO₂ content of 93%, a specific gravity of 4.0, and a typical median particle size of approximately 0.36 µm.
Its surface treatment is designed to support durability and dispersion. Chemours attributes its durability to a continuous silica coating around the TiO₂ particle and its dispersion characteristics to alumina and organic surface treatments.
Where R-706 can fit
R-706 may be considered when the coating formulation places greater emphasis on:
- Exterior durability
- Gloss retention
- Dispersion
- Wet-in
- Automotive coatings
- Industrial coatings
- Architectural coatings
For manufacturers comparing R-902+ and R-706, the decision should be based on the required coating performance rather than simply comparing TiO₂ percentage.
Ti-Pure R-104: High-Performance TiO₂ for Plastics and Masterbatches
Ti-Pure R-104 is different from R-902+ and R-706 because it is primarily designed for plastics.
The grade is specifically developed for highly loaded thermoplastic masterbatches where melt flow, tint strength, opacity, and processing behaviour are important.
R-104 offers:
- High tint strength
- Very blue undertone
- High opacity
- Excellent thermoplastic dispersion
- Minimal effect on melt flow
- Excellent lacing resistance
The grade contains a minimum of 97% TiO₂ and has a typical specific gravity of 4.2.
For plastic compounders and masterbatch manufacturers, these characteristics can be particularly relevant when high pigment loading is required without creating unnecessary processing difficulties.
Why R-104 is relevant for masterbatch manufacturers
In highly loaded masterbatch production, pigment concentration can affect viscosity, melt flow, dispersion, and final colour.
R-104 is designed around this challenge. Its combination of high tint strength and processing characteristics makes it suitable for formulations where manufacturers need strong optical performance while maintaining practical processing behaviour.
It can therefore be considered for applications involving:
- Thermoplastic masterbatches
- Plastic compounding
- High-pigment formulations
- PVC and other polymer systems
- Applications requiring bright white colour
Ti-Pure R-105: Durable TiO₂ for Outdoor Plastics
Ti-Pure R-105 is also a chloride-process rutile TiO₂ pigment, but its primary focus is outdoor plastic applications.
Chemours specifically recommends R-105 for outdoor plastics, including PVC window profile applications.
The grade combines:
- Brightness
- Neutral undertone
- Moderate tint strength
- Durability
- Dispersion
- Processing performance
R-105 has a minimum TiO₂ content of 92%, with silica and alumina surface treatments designed to improve durability and interaction with the surrounding polymer matrix.
R-105 for outdoor PVC applications
Outdoor plastics face continuous exposure to sunlight, UV radiation, temperature changes, and environmental conditions. The surface treatment of TiO₂ can therefore have an important influence on long-term appearance and performance.
R-105 uses silica encapsulation technology to reduce interaction between the TiO₂ surface and the polymer or additives. Chemours states that this helps minimise surface deterioration such as chalking and crazing in outdoor applications.
This makes R-105 particularly relevant for manufacturers producing:
- PVC window profiles
- Outdoor plastic products
- Exterior plastic components
- Durable polymer applications
- Applications requiring colour and gloss retention
R-902+ vs R-706 vs R-104 vs R-105
The most important difference between these four grades is their intended application.
| Ti-Pure Grade | Primary Application | Key Performance Focus | Typical Use |
| R-902+ | Coatings | Balance of hiding, gloss, chalk resistance & dispersion | Architectural, industrial & powder coatings |
| R-706 | Coatings | Gloss, durability & dispersion | Architectural, automotive & industrial coatings |
| R-104 | Plastics | Tint strength, opacity & melt-flow behaviour | Thermoplastic masterbatches |
| R-105 | Outdoor plastics | Durability, brightness & neutral undertone | PVC profiles & outdoor plastics |
This comparison shows why TiO₂ grade selection should start with the end application.
A coatings manufacturer may narrow the choice between R-902+ and R-706, while a plastics manufacturer may need to compare R-104 and R-105 depending on whether processing performance or outdoor durability is the primary requirement.
Dispersion: Why It Matters in TiO₂ Selection
Dispersion is one of the most important factors when selecting titanium dioxide.
Even a high-quality pigment cannot deliver its intended optical performance if it is not properly dispersed throughout the formulation.
Poor dispersion can result in:
- Reduced opacity
- Uneven colour
- Lower gloss
- Processing problems
- Higher energy requirements
- Inconsistent finished-product quality
R-902+ is known for strong dispersion characteristics in coating systems, while R-706 is designed to provide excellent dispersibility and easy wet-in.
For plastics, R-104 and R-105 are formulated around polymer processing requirements, making their dispersion behaviour relevant to masterbatch and extrusion applications.
Opacity and Tint Strength
Opacity determines how effectively TiO₂ hides the substrate, while tint strength indicates the pigment’s colouring efficiency relative to a reference.
These characteristics are not identical.
A formulation engineer should consider:
- Required hiding power
- Pigment loading
- Base resin or binder
- Desired colour undertone
- Processing conditions
- Final product requirements
R-902+ is positioned as a versatile coatings pigment with strong hiding and tinting performance. R-104 provides high tint strength and high opacity for thermoplastic applications, while R-105 combines brightness with a more neutral undertone for outdoor plastics.
Chalk Resistance and Weatherability
For outdoor applications, long-term durability is often more important than initial whiteness alone.
Chalking can occur when the surface of a coating or plastic deteriorates under environmental exposure. UV stability, pigment surface treatment, resin chemistry, and formulation design all influence outdoor performance.
R-902+ offers a balance of chalk resistance and optical performance for many coatings applications, while R-706 is specifically positioned around durability and gloss retention.
For outdoor plastics, R-105 uses silica encapsulation technology designed to improve durability and reduce surface deterioration.
Manufacturers should still evaluate the complete formulation and conduct application-specific testing before selecting a commercial grade.
How to Select the Right Chemours Ti-Pure Grade
A simple application-first approach can make the selection process easier.
Choose R-902+ when:
You need a versatile TiO₂ pigment for interior or exterior coatings with a balance of hiding, gloss, chalk resistance, and dispersion.
Consider R-706 when:
Your coating requires strong durability, high gloss, easy wet-in, and good dispersion for demanding architectural, industrial, or automotive applications.
Consider R-104 when:

Consider R-105 when:
You manufacture outdoor plastics, particularly PVC profiles, and need brightness, neutral undertone, processing performance, and improved durability.
What Procurement Teams Should Check Before Ordering
Industrial procurement teams should not select a TiO₂ grade only on price per kilogram.
The effective formulation cost can also depend on:
- Required pigment loading
- Dispersion time
- Processing energy
- Reject rates
- Colour consistency
- Production throughput
- Weathering requirements
- Storage and handling
- Supply availability
- Packaging requirements
- Application-specific technical support
A grade with a higher purchase price may have different formulation economics depending on the required dosage and processing performance.
Before placing a bulk order, manufacturers should also verify the current technical data sheet, SDS, packaging availability, batch specifications, and application suitability with their supplier.
